i UPGRADED MY GA-Z170X-Gaming G1 TO F20b BIOS this morning. Now I have no PCI recognition on 980ti. No matter what I try they are not seen. Booting using onboard intel works and the device manager in windows only shows the onboard as being connected as display adaptor. Any ideas? reset BIOS to default and all that but nothing. Can't flash older BIOS over this one and my system seems to have programmed the second BIOS to the same version so can't use that. Any way I can force it to restore older using usb in back? Thanks for any help.
